Key findings
• Gullies are vulnerable to ongoing erosion because they concentrate runoff and have steep walls. Today’s gullies are a legacy of past grazing impacts.
• The dominant source of sediment from gullies in grazed rangelands is erosion of gully walls, while head cut erosion also contributes.
• Sediment losses are lower from gullies with more vegetation cover.
• Gully erosion rates are correlated with annual rainfall.
